Proton-controlled inter-conversion between an achiral discrete molecular square and a chiral interpenetrated double-chain architecture

Abstract

Proton-controlled reversible inter-conversion between an achiral CuII molecular square, and a 1D spontaneously resolved chiral interpenetrated double-chain with Cu4 cavities, based on bis(3-propionyloxy)-1,5-diazacyclooctane (H2L), has been successfully achieved.
